Gibson CFT Oval Superflow Mufflers Reviews

I used a local muffler shop to install this, they did a good job though. My gas mileage has increased a good bit as well had an incremental increase in power and torque, it's hard, really, to gauge these without a dyno. It sounds great, everyone loves it. Most say it "sounds nothing like a 4Runner". My only complaint is the baffle within the muffler as this is a single entrance and exit muffler but the muffle itself has a dual chamber construction inside. Noise will be fixed with insulation.

Flowmaster Super 44 Series Mufflers Reviews

Upgraded my 5.4 3v F150 from 2.25" true dual exhaust with Dynatech max long tubes and cats with super 40s to 2.5" with high flow cats and super 44s. The sound isn't as loud but more throaty with a little more rumble and the interior resonance was reduced drastically. Exhaunt flows much better now. I can't tell if my low end torque changed much but passed 4000rpm there is a big difference.

I got the pipe diameter and size of the original muffler, then ordered this one based on required size. The original system was stainless and both pipes were in very good shape, so I was looking for a replacement muffler that as not going to break the bank. The vehicle is 18 years old, so the only other parts that I found were CAT-back with both pipes included priced almost 6X the muffler alone. The old muffler was cut out and this one welded in, and the system is good as new.
